A WINTER WEATHER ADVISORY has been issued for all of central and northern Montana, down through the southwest part of the state.
A WINTER STORM WATCH has been issued for south-central and southeast Montana.

Another storm will spread snow throughout much of Montana from Wednesday into Thursday. This storm will have a wide impact across most of the state. Areas of snow will develop Wednesday morning. A few raindrops could mix in initially around the Helena area. Snow will become more widespread through Wednesday evening, and travel conditions will deteriorate. The flakes will continue to fly through the night into Thursday morning. Temperatures will drop through Wednesday into Thursday morning, with a mid winter feel. By Thursday afternoon, skies will become partly cloudy as the storm moves away. Friday, another round of snow will develop across much of the state by afternoon. Snow will continue through Friday night into Saturday. A significant amount of snow, possibly in excess of 6" in the lower elevations and more than 12" in the mountains will accumulate by late Saturday. Arctic air, some 30-50 degrees below normal, will move into the state for this weekend. Recold cold is likely throughout the weekend, and much of the state could drop below 0 on Saturday night. Temperatures will slowly warm early next week, returning to more normal temperatures for late October.
